REVERSING-VALVE.

Specification of Letters Patent.

Patented Dec. 14, 1920.

Application filed October 21, 1918. Serial No. 258,988..

Be it known that we, FREDELLIA H. MoYE'R and GEORGE -E. THAGKRAY, both citizens of the United States, and both residing in the borough of Westmont, in the county of Cambria and State of Pennsylvania, have invented certain new and useful Improve. ments in Reversing-Valves; and we do hereby declare the following to be a full, clear, and exact description of the invent1on,-such 'as will enable others skilled in the art to valve hood or valve proper, which may be of oscillating or D type, is within the easing' and subjected at all times to the heat of the passing gases on both sides of said valve in such a way as to lead to their warping and cracking, causing inoperativeness and quick destruction.

It is one of the objects of our invention to provide a reversing valve, the outer portion of'which is exposed to the atmosphere so that it is always cooled thereby, thus prolong its life and maintaining its operableness.

Another particular feature of our construction resides in the use of separate disk valves for the flue which is not controlled by the D-valve proper and in this construe tion one of these disks is operative, dependent upon the position. of the main valve, and when the main valve controls the two right-hand ports or passages or the two left-hand ones, the disk valve controls the other passage-or port.

In our construction we equip the main valve with two separate disk valves which are attached to and moved with the main valve, being hung from a light frame-work secured to the main valve. Our reversing valve is adapted both for controlling the gas passages or the air passages of a regenerative furnace, and also the passages to the stack.

Our air reversing valve has separate valve disks hung from a frame secured to the like characters refer to like parts main or D-valve and these disks may be connected to a ralsing or lowering mechanism so that when either ofthese separate valve disks is'over the air port which supplies air to the regenerator, it may be raised or lowered to increase or decrease the sup:

ply of air, thus acting both as a part of.

the reversing'valve and as an air controlling valve; .The separate valve disks for the gas valve, however, are not provided with lifting mechanism but are preferably arranged so that they move with and are loweredor lifted as they seal or open the port during the operation of the valve. For

the ordinary regenerative furnace having one gas regenerator and one air regenerator at each end, two gas reversing valves of our construction are required, but only one air reversing valve, as will be more fully described hereinafter.

Having thus given a general description of our invention, we will now refer to the annexed two sheets of drawings in which,

Figure 1 is a top plan view of our improved reversing valve adapted to be used as either a gas valve or an air valve. Fig.

2 is a vertical longitudinal sectional elevation takenon the line IIII of Fig.1. Fig. 3 is a vertical transverse sectional elevation taken on the line IIIIII of Fig. 2. Fig. 4 is a top plan view of our valve showing a slightly modified form of separate valve disks more particularly adapted to regulate or control the air, although it could also be used for controlling gas, if desired, in which case. the valve disks would be arranged to seat about the port instead of being maintained above it. Fig. 5 is a ver-' tical longitudinal sectional elevation taken on the lineV-V of Fig. 4 and Fig. 6 is a vertical transverse sectional elevation taken on the line VI-VI of Fig. 5.

Referring now to the various characters of reference on Figs. 1 to 3 inclusive: 1 is the base casting formed with upwardly extending flanges 2 aroundthe edges thereof, which, in connection with the other flanges serve to retain water, sand, or other sealing medium in the space between said flanges, 8 is a flue opening or port adapted to connect with-the chimney stack through which the products of combustion ultimately pass, 4 is a port or passage connecting with the gas regenerator, and 5 isa flue or port adapted to connect with a source of producer gas or operative position.

similar gas supply. 6 is the valve hood which is shown as of D-form with a refractory lining, 7 is the base ring of the valve hood provided with downwardly extending flanges adapted to be submerged in the sealing medium to make the valve tight when in 8 is a' central cover within the hood, preferably lined with refracto'r material, as illustrated, which is adapte to cover the sealing groove and prevent unnecessary evaporation of water, or other sealing fluid, when the valve is in position as illustrated in Fig. 2. -9 are axles mounted at the ends of the valve hood, provided with bearin s 10 and wheels 11 mounted thereon, and t e openings in the base of side of the valve, which have raised ortions 15 and depressed portions 16 unite by inclines,the construction beingsuch that as the valve is traversed longitudinally the wheels roll up the inclines, thereby lifting the sealin portions ofthe base ring 7 above the base anges and out of the sealing fluid, and as the movement continues. the valve passes over the inclines on the track to its next position and the flan ed base rings again are submerged and sealed in their new position. 'The track is arranged with depressions, elevations and inclinations so that the downwardly projecting flanges of the hood base ring are carried over the flanges of the base castin without interference and set in the new position. The hood is further provided with brackets shown as an Ice 17 secured thereto, with sockets 18 provided in the ends thereof, in which sockets the hangers 19 are adjustably mounted and secured to the ears 20 of the se arate valve disks 21. An eye-plate 22 is provlded on the top of the hood for the purpose of securing a counterbalancing construction to the same or for the purpose of lifting the hood when desired, and other similar eyes are also secured to the up er ends of the hood, as illustrated. In

or er to move the valve, I provide an operuid under pressure. Referring now to Figs. 4, 5 and 6: The

pan or base casting is 26, the upwardly extending flanges of the same are 27, 28 is a flue o ning or passage to the r enerator, 29 is a no opening or passage to t e stack and 30 is a flue opening or passage to the other regenerator which is controlled b the valve. The valve hood proper is 31, the anged base ring thereof is 32,. the central cover within of the hood to which the frame-work 43 is secured and hinged, as shown. The outer ends of frame-work 43 are, 44, from which hangers 45 are swung, their upper ends be-. ing provided with links or eyes 46, provided with a .flexible or other connection to a screw wheel or other apparatus for raising and lowering the frame-work 43 and conse-' quently raising or lowering the valve disks 47,wh1ch valve disks are each provided with a central rib or flange 48 to which the hanger 45 is ivoted, as illustrated. The hood is provi ed with eye-plates 49 secured-to the top thereof for the .purpose of lifting or counterbalancing the same, The valve is moved by means of the o erating plunger 50 and the cylinders there or which may be actuated by any suitable fluid under pressure. 51 isa bracket arm, mounted on the plan r 50, and 52 are brackets secured to the s1de,of the hood adapted to contact with.

the bracket arm 51 for the urpose of moving the valve backward or orward.

he valve hood may be made of metal such a? plate iron or plate steel for the pur ose ghtness and may either be unline or provided. with a refractory lining, preferably of light material in order to minimize the weight of the moving parts.

The operation of our valve is as follows:

Referring now to Figs. 1, 2 and 3: The valve and 4, the regenerator flue is then connected to the stack flue 3 and the flow of ofi-gases passes into the stack flue 3 and then to the.

stack. While the valve is in its right-hand position as shown in Fig. 3, the right-hand valve disk 21 han s in the air, as illustrated, whereas the leftand valve disk 21 closes the opening 3, as shown, thus preventing the flow of atmospheric air to the stack.

Referring toFigs. 4 5 and 6: This valve is particularly adapted to act as an air control valve and when in the" position shown in Fi 5, is adapted to connect the regenerator ue 30 with the stack flue 29, while at the same time the space between the lefthand disk 47 and the upper flange base ring 27 allows air to ass into the other regenerator flue 28. e separate valve disks 47 can be raised or lowered by any suitable means to allow more or less air, or to entirely cut oil the supply. On reversal, the main valve connects the regenerator port 28 with the stack flue 29 and the right-hand disk 47 controls the air supply to the regenerator port 30.
